as a reading lamp for persons seated cnearfthe Patented Feb. 20, 1945 1 TED Application September 23, 1942,;Serial H9360 I f 8 Claims. (01.1 210451) The present invention relates to lamps, especially for domestic' use, and may be embodied in varioustypes, as for instance, :a'floor llamp a table hempw a piano lamp, 'or the like;

' conducive to a clear understanding of the objects of the invention, it is noted that the-ordimn'y indirect lamp admits of effectiveuse only when positioned near the region where maximum illumination is required, and this entails the shifting of lamps, as for instance, for cardp'laying, from their normal position near the wall tothe and IQ for the bulbs rest'in the well :ofthe' rim l and nuts 20 on the studs of said switches serve to-clamp the rims I 4 and -together, as well'as to retain the switches in place; The operatin :knobs 21 :of the switches protrude-downward "through the nuts f erably three tangentially extending sockets'--22, disposed in a [horizontal plane, each mounting "a center-of the room, where the lamp is in the way I 01 the players and' aptto be upset."

' An object of the present invention is to provide a lamp which inherentlyafiords' the maXimum indirect illumination at regions remote therefrom-so that a :setof such'lamps-in a room v 1 will proiect light for maximum :illuminationat the main area of the :room .and 'will afford a decorative pattern of light at and near the walls Anotherroh'ject is to provide-Ta lamp, which in addition to the utility above setiorth, sis useful Another'object is to provide a lamp which performs the various functions above enumerated, without :glare and without-necessitating a freakishorun-coriventional appearance; L i

Referring :now 'to the drawing, thelamp com-- prises a standard III which may be conventional and'upon the upper end-of which is carried a hub' I I which in turn carries the various shade, shield,

' bulb and baflle elements to be described hereinafter. The hub is preferably made up of two complementary cupped elements including a lower shallow dished member l2 and an upper deep cup member I3, said members having outstanding rims l4 and I5 respectively, the upper of said rim elements being preferably dished as at IE to restupon the lower rim element and to.

afford an annular clamp c for the inner periphery of the dished diffusing shield [1 preferably of opal glass. Desirably, the control switches I8 The hub fl 1" preterably mounts aplural'ity, pref,-

Mounted on the hub? isalaterally extending or bracket $24 upon; which is supported'k-i'n any suitable manner as-by bolt 25 andnut'261a socket 2'! extending obliquely inwardand upward .inthe axialp lane of the standard wand hub H,

I desirably at an:angle-:of 45degrees., In-saidsocket "2331s mounted a bulb 2 8 which desirably :has an inner DIP/0111381 .mirror surface ,on its: paraboloid wall; the most luminouspoint of the filament beling substantially at the'lfocus-o'fsaid; paraboloid,

t to projectia beam that'diverges'but ;little.- The bulb describedis an article of commerce and designated by me a reflector bulb. .The circuit to -the1refiector-bulb is controlled by switch l9.

7 Mounted upon the upperendof the huh I I there I are desirably three wire. struts 29 extending-outward and upward and supporting upon the up- [perendthereoi :a horizontal bafiie ring 30 which 30 one of various possible embodimentsoftheseveral v t .floor .lampembodying theiinvention and'illustratmay bezs'oldered, welded orriveted thereto. The baflle ring has a series of parallel bafileeplates 3| thereaoross, each of said plates being desirably inclined at the :same angle. as theinclination of p the reflectorbulb axis and-its socket. The outstanding rim 320i thebaffle ring supports the usual silk or parchment lamp shade, 3 3,,which encompasses the various rbulbs, the hub, 'the difiusingshieldand the baffle ring. .i

. When the switch =l8- is turned on to place the small bulbs 2,3 into circuit, the lamp servesas :a

reading lamp by whichglareless illumination penetrates the diffusing :shield 1| 1. The bulbsalso efiect'ithe desired ornamental luminosityzofgthe shade 33.

When switch I 9 is thrown to close the circuit to the reflector bulb 28, the beam from the latter is projected obliquely upward through the baffle ring 30 to the ceiling and-thence reflected obliquely downward with relatively little spread. Accordingly, substantial illumination is projected by the lamp standing in a corner of the room to'a table in the middle of a room. The bafiies plates 35 of ring 30 shield the eyes of a person standing near and'above the lamp. The oblique plates 3i also disperse a small amount of light downward to.

l8 and I9 are on, the-lamp cidedly ornamental and scientifically correct illuminating efiectsmay be attained in the main area of the room,f while yet affording proper illumination for reading by those near the lamp.

Changes could be made in the above construction and difierent embodiments of this invention could be made without departing from the scope of the claims. It is intended that all matter contained in the above description or shown in the accompanying drawin shall be interpreted as illustrative and not in a limiting sense except to the extent that such limitations are imposed by the appended claims.
